Super Seven

Trade descriptions say the material comes only from Espírito Santo, Brazil, from a mine that has since closed; a seller text quoted on Mindat in 2003 made this claim, and the retailer Pascle repeats the Espírito Santo origin. Pascle adds that similar-looking stones now come from many places and are sold under the same name, listing Brazil, Madagascar and India. Mindat contributors described the material as Brazilian amethyst.

There is no mineralogical definition of Super Seven, so the name itself cannot be confirmed by testing; what can be tested is the quartz host (hardness 7, refractive index 1.544 to 1.553) and the individual inclusions. According to Mindat manager Alfredo Petrov, the examples he saw on sale never had all seven claimed constituents, the "cacoxenite" was really goethite and the "lepidocrocite" was hematite. The Quartz Page likewise reports that red inclusions in amethyst once called lepidocrocite have been found to be hematite. Mindat founder Jolyon Ralph called the name a marketing term and identified one specimen offered as Super Seven as parallel-growth smoky amethyst quartz.

IGS lists no special care instructions for quartz. The retailer Pascle advises wiping pieces with a soft cloth after wear and not storing them in direct sunlight for long periods, because the purple of amethyst can fade in strong light.

The names Super Seven and Melody Stone were already in trade use by 2003, when Mindat members discussed a seller description of the stone as a combination of seven minerals found only in Espírito Santo, Brazil. The retailer Pascle states that the name began with the crystal author known as Melody, who introduced and named such crystals from a Brazilian mine in her writing, and that the original mine is said to have stopped producing.

Retailers present Super Seven as a symbol of harmony and unity: Pascle says it is regarded as representing "harmony" and "integration" and is kept as a charm for bonds between people, while stating that these meanings are not scientifically proven. According to a seller text quoted on Mindat, it was said to enhance psychic abilities; Mindat contributors dismissed such claims as marketing.
